Does the Diameter of a Tungsten Wire Matter?

The regular sizes of tungsten wire can vary depending on the manufacturer and the intended application. However, some common sizes include:

Diameter: the diameter typically ranges from 0.01 mm to 3 mm. The specific diameter needed depends on the desired application, as well as the required electrical and thermal properties.

Length: the wire is typically supplied in spools of varying lengths. 

Gauge: the gauge of the wire refers to its diameter, and is often expressed in millimeters or in American Wire Gauge (AWG) units. For example, a black tungsten wire with a diameter of 0.5 millimeters would have a gauge of approximately 22 AWG.

Does diameter of tungsten wire matter?

The diameter of a wire does matter, as it affects a number of the wire's physical and electrical properties. Some of the factors that can be impacted by the diameter of a wire include:

Resistance: the resistance of a wire is inversely proportional to its cross-sectional area. This means that a wire with a larger diameter will have a lower resistance than a wire with a smaller diameter.

Current carrying capacity: the current carrying capacity of a wire is proportional to its cross-sectional area. This means that a wire with a larger diameter can carry more current than a wire with a smaller diameter without overheating.

Strength: the strength of a wire is proportional to its cross-sectional area. This means that a wire with a larger diameter will be stronger and able to support more weight than a wire with a smaller diameter.

Flexibility: the flexibility of a wire is inversely proportional to its diameter. This means that a wire with a smaller diameter will be more flexible and easier to bend than a wire with a larger diameter.

Therefore, when choosing a wire, it is important to consider its intended application and select a diameter that provides the desired balance of resistance, current carrying capacity, strength, and flexibility.
